Jean Moulin lived several lives: unifier of the French Resistance, martyr tortured by the Gestapo, forgotten after the war, and then hero. From obscurity to prominence, Jean Moulin's name has remained linked for 70 years to that of his executioner, Klaus Barbie. This historical connection has contributed to the Resistance fighter's enduring legacy. The film retraces the paths of Jean Moulin and Klaus Barbie, head of the Gestapo in Lyon, from November 11, 1942, to June 21, 1943, the date of Jean Moulin's arrest.
